Ok, so I bought a nib ST pro about a year ago. I wasn't sure if it was a good choice at first, but as my ability to hit smooth shots improved I've become absolutely addicted to it. The speed and flow of the game is awesome.
So I'm ready to buy a second.
I've played GOT pro and premium. I like the pro better. I really like the game but I don't know a damn thing about Game of Thrones.
I've had a little time on GB pro at Allentown. I love the theme and know the movies. It's a very different style from ST and that's no problem. I'd buy the premium.
My timing is January 2017...I'm not an early adopter and prefer to wait until bugs are worked out.
I will also add that I like deep rules and buried "stuff" that turns up only after you've spent a lot of time playing.
So...pros and cons?
